The goal of this study was to determine the magnitude of
glenoid retroversion that can be corrected with asymmetric
reaming that maintains the ability to implant a glenoid
component without allowing any peg penetration of the
glenoid vault. We hypothesized that increased retroversion
will require smaller glenoid components for successful
implantation when the glenoid is surgically corrected and
that correction beyond 20 of retroversion is not feasible
without peg penetration. With the increasing interest in
gender-specificity in hip and knee arthroplasty,
we investigated potential differences in choosing glenoid
implant sizes according to gender. The hypothesis was that
women would be more likely to require smaller glenoid
prostheses than men.
